美国心脏协会基础生命支持课程培训对低年资护士胸外按压效果的研究

目的探讨美国心脏协会(American Heart Association,AHA)基础生命支持(Basic Life Support,BLS)培训对低年资护士胸外按压效果的研究。方法对2014年3月~2016年3月新入职的低年资护士,按随机数字表法分为观察组和对照组,观察组采用AHA模式进行BLS培训,而对照组采用传统的模式进行培训,观察组和对照组同时在1年内完成BLS培训。1年后由护理部统一对低年资护士进行胸外按压考核,对两组护士的按压频率、深度和回弹情况进行评估。结果两组5个循环的按压频率逐渐降低,两组频率比较差异无统计学意义(P0.05);观察组有效按压比例高于对照组(71.71%vs 60.56%,P0.05)。两组的按压深度逐渐降低,第5个循环的深度差异有统计学意义(P0.05);观察组的有效按压深度比例高于对照组(73.14%vs 64.23%,P0.05)。两组的CPR按压回弹率比较观察组大于对照组,差异具有统计学意义(P0.05),观察组总体回弹比例高于对照组(95.8%vs86.5%,P0.05)。结论 AHA-BLS培训能更有效提高低年资护士胸外按压的质量,提高院内心肺复苏的水平。

Study on the effect of external chest compression by junior nurses after the training of basic life support courses of the American Heart Association

Objective To investigate the effect of external chest compression by junior nurses after the training of basic life support(BLS)of the American Heart Association(AHA).Methods From March 2014 to March 2016,the newly recruited junior nurses were divided into observation group and control group according to the random number table.The observation group was given AHA model for BLS training,and the control group was given traditional model for training.The observation group and the control group completed BLS training within one year at the same time.One year later,the junior nurses were assessed on the external chest compression by the Department of Nursing.The frequency of compression,depth and resilience of the two groups of nurses were evaluated.Results The compression frequency of 5 cycles was gradually decreased in both groups,with no statistically significant difference between the two groups(P>0.05);the effective compression ratio in the observation group was higher than that in the control group(71.71%vs 60.56%,P<0.05).The depth of compression in the two groups was gradually decreased,and the difference of the depth of the 5th cycle was statistically significant(P<0.05);the ratio of effective compression depth in the observation group was higher than that in the control group(73.14%vs 64.23%,P<0.05).The CPR compression resilience rate in the observation group was higher than that in the control group,and the differences were statistically significant(P<0.05).The overall rate of resilience in the observation group was higher than that in the control group(95.8%vs 86.5%,P<0.05).Conclusion AHA-BLS training can effectively improve the quality of external chest compression by junior nurses and improve the level of hospital CPR.
